Pok?mon the movie

At a desert resort city by the sea, Ash, Pikachu, and their most recent friends encounter Hoopa, the Mythical Pok?mon who can summon anything with its magic rings. However, Hoopa is not itself--long ago a brave hero stopped Hoopa Unbound--Hoopa's real form--from going on a destructive rampage. Team Rocket finds the bottle containing Hoopa's power and plans to unleash it--unless Ash and Pikachu can stop them first.
